CROSS-REFERENCES TO RELATED APPLICATIONS

This U.S. Non-provisional application claims the benefit and priority of U.S. Provisional Application No. 62/245,529, filed on Oct. 23, 2015, entitled “ACCESS MANAGER SESSION MANAGEMENT STRATEGY,” the content of which is herein incorporated by reference in its entirety for all purposes.

BACKGROUND

Generally, the present application relates to data processing. More specifically, the application is related to techniques for managing sessions in an access management system.

Modern businesses rely on a variety of applications and systems that control and generate information that is critical to business operations. Different applications often provide different services and information, and different users may require access to different levels of information within each system or application. The level of access that users are granted may depend on the role of the user. For example, a manager may need access to certain information about employees that report to him, but it may be improper for that manager to access the same information about those whom he reports to.

Earlier less sophisticated applications incorporated access management business logic directly into the application code. That is to say, each application would require users to have a separate account, separate policy logic, and separate permissions, for example. Furthermore, when a user is authenticated by one of these applications, this authentication remains unknown to other applications in the enterprise because the fact that authentication with the first application has taken place is not shared. Thus, there is no concept of trust between applications using different systems for authentication and access control. Engineers quickly realized that having an access management system for each application in an enterprise was much like having a gas station for each car, and determined that authentication and access control would be more efficiently implemented and managed as a shared resource. These shared resources became known as an access management systems.

Access management systems often use policies and other business logic to make a determination regarding whether a particular access request should be granted to a particular resource. Upon making a determination that access should be granted, a token is provided to a client (e.g., client application at a device) of the requestor. This token is like a key that can be used to open a door that guards restricted data. For example, a user may attempt to access a human resources database to gather information about certain employees such as salary information. The user's web browser at a client makes a request to the application, which requires authentication. If the web browser does not have a token, the user is asked to log in to the access management system. When the user is authenticated, the user's browser at the client receives a token that may be used to access the human resources application.

In an enterprise, users (e.g., employees) typically may have access to one or more different systems and applications. Each of these systems and applications may utilize different access control policies and require different credentials (e.g., user names and passwords). A user wanting to access multiple resources protected by an access management system may need to be authenticated by credentials provided to the access management system. A successful authentication gives the user authorization to access the protected resources, based on their assigned access privileges.

Upon authentication, the access management system may establish a session (“user session”) to provide the access granted to the protected resource(s). For a user session, the access management system may maintain session information at a computing system (e.g., server computer) for the user session. The session information maintained by access management system may be referred to as a server-side session. The access management system may store session information for the server-side session that defines the access granted to the user and the constraints of the session. The session information for a server-side session may be mapped to a client which is provided with a token. In the instance where a SSO session is established, the access management system enforces access for SSO based on the token.

If a user wants to access multiple resources protected the access management system, the access management system may determine whether the user is authenticated to access the multiple resources requested by a user. In some instances, authentication of a user for one resource may suffice for accessing other resources, otherwise the access management system may request additional credentials from the user. Upon authentication to access multiple resources, the user may not need to re-authenticate to access additional resources. In such instances, the access management system may maintain a single session, such as a single sign-on session (SSO), that provides a user with access to multiple resources after authentication.

Some access management systems may utilize different storage techniques to manage (e.g., create, read, update, or delete operations) session information for a session. Session information may include information about the user and the user session for which the user is authenticated. Managing session information may include accessing an identity store to query information about user. However, once information is accessed from the identity store, the access management system may not need to access the information for subsequent accesses by the user for the session. An access management system may incur performance overhead from repeated access to the identity store for information that rarely changes.

After authentication of a user to establish a session, an access management system may update session information for subsequent accesses to a resource. Subsequent accesses may result in determining authorization and/or performing additional authentication (e.g., step-up authentication), either of which cause session information to be updated.

Updating session information may cause significant performance and/or memory usage overhead. For example, an access management system implemented by a computing system having multiple computing nodes, may implement locking techniques, such as distributed locking, to permit session information to be updated, even if the update is a timestamp. In some instances, distributed account locking may be performed to update session information. The locking technique may cause the access management system to encounter performance issues to implement locking where storage is shared in a distributed fashion. Based on the number of attributes and the group memberships that are stored for a user in an identity store, each session belonging to specific user may be duplicated for the session. If a user's status changes in an identity store, each of the sessions needs to be identified and deactivated to enable the sessions to be updated. In some instances, session aggregation and updates may be performed across computing nodes of an access management system.

Where distribute cache is implemented to store session information, the session information may be evicted from memory and serialized to a backend session database based on cache eviction policy. Updating session information that is currently serialized to a database can cause huge performance overhead for the access management system. In some instances, even when different storage techniques are implemented, session information may be replicated for multiple sessions that exist for a user on multiple clients. Memory may need to be optimized on a per session basis, thereby contributing to memory usage overhead to maintain session information.

BRIEF SUMMARY

The present disclosure relates to managing sessions in an access management system. Specifically, techniques are disclosed for managing session information stored by an access management system.

Techniques may be implemented, such that the method for managing and storing session information may by dynamic, changing based on one or more characteristics of the session. Session information that changes less frequently can be managed through a data store in a distributed, scalable manner optimized for reading and modification. Session information that changes frequently may be managed by sending the session information to the client requesting access so that the session information does not need to be maintained by the access management system. Techniques are disclosed to show how session information is updated and the frequency in which the session information is updated. Certain embodiments may enable a decrease in computing performance overhead and/or memory usage overhead caused by managing session information (e.g., performing authentication or determining authorization to access a resource) for a session according to techniques disclosed herein.

An access management system can improve management of a session (e.g., server-side session) by storing session information for a session based on the attributes of the session information. Session information may include, without restriction: 1) authenticated user subject information obtained from a user identity store (e.g., identifier of the identity store used for authentication, user identifier, user domain name, user GUID, and group membership for user); 2) list of partners accessed in session; 3) IP Address of the client device; 4) authentication Level; 5) authentication scheme; 6) authentication timestamp; and 7) application domain information for accessed resource. Session information for a session may be designated into two different categories: 1) session information that does not change often or that rarely changes during an active session; and 2) session information that changes frequently during an active session.

Session information that does not change often or rarely changes may be stored in highly scalable distributed cache for optimized concurrent reads. The data for the session information can be indexed by an identity store name and the domain name (DN). Examples of session information that does not change often may include information about the authenticated user subject.

Session information that changes frequently can be stored using a variety of different techniques. Examples of such session information may include list of partners accessed in session; Internet protocol (IP) Address of the client device; authentication level; authentication scheme; authentication timestamp; and application domain information for one or more accessed resources, as indicated above. One technique to store session information that changes frequently can be to implement a scalable distributed cache optimized for frequent updates.

Another technique for storing session information that changes frequently can be through a sequence of communications between the client and the access management system. Using this technique, session information can be passed to a client via a response. This can be considered as a signed access claim. The client would make sure that the information is fetched from the device and passed back to the access management system during subsequent accesses This session information must include identity store identifier and DN of the authenticated user. Using this signed access claim, the access management system would be able to determine a server-side session using information in access claim and looking up the subject information from distributed cache. During subsequent authorizations there may not be a need to update subject information. All the information to be updated may be part of access claim sent by the client. The updated claim may be sent back to client by the access management system. In this case updating the claim sent by the client and sending the claim back to the client may not cause performance overhead. Since the access management system does not store session information that is included in the access claim, the access management system may not need to implement distributed locking, which may contribute to performance overhead.

In the techniques described above for storing frequently changing session information, the sessions may be referring to subject information, which can be retrieved from cache or from user identity store. Even if same user logs-in from different clients/devices, only single subject information may be available in the cache; which will be shared by all sessions of same user. Also this same identity store information and user DN may be part of all the access claims for a user. With the approaches described above, session information may not be stored per session for a unique user. There may be only a single entry for all the sessions created for same user. If server-side session usage tracking is required, then a session-per-user login can be created which would refer to common subject information. This can reduce the server-side session footprint to great extent and optimize memory utilization of the access management system. If the user account is locked, the session information may be updated in user identity store. At the same time only a single entry in the cache may be invalidated if it exists. All the sessions for the same user may be invalidated automatically.

In some embodiments, an access management system may include a computer system that is configured to implement methods and operations disclosed herein. A computer system may include one or more processors and one or more memory accessible to the one or more processors and storing one or more instructions which, upon execution by the one or more processors, causes the one or more processors to implement methods and/or operations disclosed herein.

The present disclosure relates generally to providing single sign-on (SSO) access. A SSO session may provide a user with access to one or more systems after authentication of credential information (e.g., a username and a password). Access to a system may provide access to one or more resources. Resources may include any item managed and/or stored by a computing system, such as an application, a document, a file, electronic content, and/or the like. A resource may be identified by a uniform resource locator (URL) or other data indicating a source of the resource.

I. High-Level Overview of Access Management System for Managing Sessions

Some embodiments, such as systems, methods, and machine-readable media are disclosed for managing session information. FIG. 1 illustrates a system 100 in which session information can be stored such that memory and performance usage may be minimized, thereby reducing the time for managing sessions across multiple clients (e.g., applications and devices).

FIG. 1 illustrates a system 100 in which a user (e.g., user 102) operating multiple clients (e.g., an application on a device or a device). User may operate a first client (e.g., device 104 or application 106 executing on device 104) to request access to resources. A user may operate a second client (e.g., device 114 or application 116 executing on device 114) Authentication of a user with access management system 140 and authorization of the user to access specific resources, may be managed by access management system 140. In some embodiments, access management system 140 may include a session engine 142 that manages authentication of a user and one or more sessions created to enable access for the user. Access management system 140 may include an authorization engine 144 to determine authorization of a user to access particular resources.

For purposes of illustration, “session” as described herein includes an SSO session; however, a session may include other types of sessions enabling access to a user. Access management system 140 may provide access to one or more resources. Access management system 140 may implement a sign-on system, e.g., a SSO system, which can establish an SSO session to provide SSO access to one or more resources.

Access management system

140 may store session information for each session created to enable a user with access. Session information may include, without restriction, 1) authenticated user subject information such as user identity information (e.g., user identifier, user domain name, user group user identification (GUID), and group membership for user); 2) list of partners accessed in session; 3) Internet protocol (IP) address of a client; 4) authentication level; 5) authentication scheme; 6) authentication timestamp; and 7) application domain information for one or more resources that are accessed. Access management system 140 may employ a variety of techniques disclosed here in for management of session information for each session.

Resources may include, without restriction, a file, a web page, a document, web content, a computing resource, or an application. For example, system 100 may include resources such as applications 120 and/or content accessible through those applications 120. A resource may be requested and accessed using an application. For example, an application may request access to a web page from a resource server based on a URL identifying a requested resource. Resources may be provided by one or more computing systems, e.g., a resource computer server that provides access to one or more resources upon authentication of user 102 in a SSO system. Although a user may be authenticated with access, each user may have different rights to access different resources. As such, authorization may be determined for each resource. Authorization may be determined for each resource server that provides a resource.

User

102 operating a client device, e.g., device 104 or device 114, may present one or more interfaces that accept input to enable a user to interact with an access management system (e.g., access management system 140). The interfaces may be accessible using an application (e.g., application 106 or application 116) executing on a device. The application and/or interfaces may be provided by access management system 140 as part of a service.

Each of device 104 and device 114 may include a computing device. The computing device may include a computing system such as one or more computers and/or servers (e.g., one or more access manager servers), which may be general purpose computers, specialized server computers (including, by way of example, PC servers, UNIX servers, mid-range servers, mainframe computers, rack-mounted servers, etc.), server farms, server clusters, distributed servers, or any other appropriate arrangement and/or combination thereof. Device 104 and device 114 may run any of operating systems or a variety of additional server applications and/or mid-tier applications, including HTTP servers, FTP servers, CGI servers, Java servers, database servers, and the like. Exemplary database servers include without limitation those commercially available from Oracle, Microsoft, and the like.

Devices

104, 114 may be implemented using hardware, firmware, software, or combinations thereof.

Each of

devices

104, 114 may include at least one memory, one or more processing units (or processor(s)), and storage. The processing unit(s) may be implemented as appropriate in hardware, computer-executable instructions, firmware, or combinations thereof. In some embodiments, access management system 140 may include several subsystems and/or modules.

Devices

104, 114 may be implemented to operate using in hardware, software (e.g., program code, instructions executable by a processor) executing on hardware, or combinations thereof. In some embodiments, the software may be stored in a memory (e.g., a non-transitory computer-readable medium), on a memory device, or some other physical memory and may be executed by one or more processing units (e.g., one or more processors, one or more processor cores, one or more GPUs, etc.). Computer-executable instructions or firmware implementations of the processing unit(s) may include computer-executable or machine-executable instructions written in any suitable programming language to perform the various operations, functions, methods, and/or processes described herein. The memory may store program instructions that are loadable and executable on the processing unit(s), as well as data generated during the execution of these programs. The memory may be volatile (such as random access memory (RAM)) and/or non-volatile (such as read-only memory (ROM), flash memory, etc.). The memory may be implemented using any type of persistent storage device, such as computer-readable storage media. In some embodiments, computer-readable storage media may be configured to protect a computer from an electronic communication containing malicious code. The computer-readable storage media may include instructions stored thereon, that when executed on a processor, perform the operations described herein.

Access management system

140 may be implemented by a computing system. The computing system may include one or more computers and/or servers (e.g., one or more access manager servers), which may be general purpose computers, specialized server computers (including, by way of example, PC servers, UNIX servers, mid-range servers, mainframe computers, rack-mounted servers, etc.), server farms, server clusters, distributed servers, or any other appropriate arrangement and/or combination thereof. Access management system 140 may run any of operating systems or a variety of additional server applications and/or mid-tier applications, including HTTP servers, FTP servers, CGI servers, Java servers, database servers, and the like. Exemplary database servers include without limitation those commercially available from Oracle, Microsoft, and the like. Access management system 140 may be implemented using hardware, firmware, software, or combinations thereof.

In some embodiments, access management system 140 may be implemented by multiple computing devices (e.g., server computers) deployed as a cluster. Each of the server computers in the cluster may be a different computing node, which may communicate with one or more clients. Each computing node may handle authentication and authorization for session management. The cluster may be deployed as part of a data center, which allows for scalability and high availability. Multiple such geographically dispersed data centers with access manager server clusters can be connected (wired or wirelessly) to constitute a multi-data center (MDC) system. An MDC system may satisfy high availability, load distribution, and disaster recovery requirements of access servers within an enterprise computer network. An MDC system may act as a single logical access server to support SSO services for access management system 140.

Access management system

140 may include at least one memory, one or more processing units (or processor(s)), and storage. The processing unit(s) may be implemented as appropriate in hardware, computer-executable instructions, firmware, or combinations thereof. In some embodiments, access management system 140 may include several subsystems and/or modules. For example, access management system 140 may include session engine 142 and authorization engine 144, each of which may be implemented in hardware, software (e.g., program code, instructions executable by a processor) executing on hardware, or combinations thereof. In some embodiments, the software may be stored in a memory (e.g., a non-transitory computer-readable medium), on a memory device, or some other physical memory and may be executed by one or more processing units (e.g., one or more processors, one or more processor cores, one or more GPUs, etc.). Computer-executable instructions or firmware implementations of the processing unit(s) may include computer-executable or machine-executable instructions written in any suitable programming language to perform the various operations, functions, methods, and/or processes described herein. The memory may store program instructions that are loadable and executable on the processing unit(s), as well as data generated during the execution of these programs. The memory may be volatile (such as random access memory (RAM)) and/or non-volatile (such as read-only memory (ROM), flash memory, etc.). The memory may be implemented using any type of persistent storage device, such as computer-readable storage media. In some embodiments, computer-readable storage media may be configured to protect a computer from an electronic communication containing malicious code. The computer-readable storage media may include instructions stored thereon, that when executed on a processor, perform the operations described herein.

FIG. 1 shows an example in which user 102 can engage in communication with access management system 140 to access resources, such as any one of applications 120 or the resources accessible through applications 120. Applications 120 may be accessible to user 102 upon successful authentication of credential information for user 102. Before one of applications 120 is accessible to user 102 at device 104, user 102 may be authenticated for a session that provides user 102 with access to applications 120. Device 104 may initiate an authentication process by requesting access from access management system 140. The authentication process may include device 104 displaying one or more GUIs to receive credential information of a user and submitting a request for authentication to access management system 140. Authentication may be established based on verifying credential information of the user 102.

In attempting to access an application, user 102 may operate an application (e.g., application 106) that manages access to a user's account via access management system 140. For example, application 106 is an access management application that may present GUIs. Using application 106, user 102 may request access to one or more resources, engage in authentication, and request modification of an authentication level.

Client devices

104, 114 may communicate with access management system 140 via one or

more communication networks

170, 130, respectively. Examples of communication networks may include a mobile network, a wireless network, a cellular network, a local area network (LAN), a wide area network (WAN), other wireless communication networks, or combinations thereof.

Communications between device 104 and access management system 140 can be received through a gateway system. The gateway system may support access management services. For example, a single sign-on (SSO) gateway may implement one or more access agents, e.g., a web gate agent, to balance and/or handle requests from clients and access management system 140.

Resources (e.g., applications 120) may be accessible to user 102 based on successful authentication of credential information. Upon receiving the credential information, session engine 142 may verify whether a requested resource, e.g., application 106, is a protected resource that requires credentials for access. Session engine 142 may request authorization engine 144 to determine whether access to a resource is protected. Upon determining that access determines that the resource is not protected, session engine 142 may grant access to a resource. Upon determining that access to a resource is protected, session engine 142 may determine authentication of user 102 based on the credential information. Upon determining authentication of user 102, authorization engine 144 may determine whether user 102 is authorized to access a resource based on access permitted to user 102. Session engine 142 may send a communication to device 104 to indicate whether access to a resource is permitted by user 102. Application 106 may be enabled to user 102 based on whether access is permitted.

Access management system

140 may provide many SSO services including management of access (e.g., granting/denying access) to resources, automatic sign-on, application password change and reset, session management, application credential provisioning, as well as authentication of a session. In some embodiments, access management system 140 can provide automatic single sign-on functionality for applications 120, such as Windows® applications, Web application, Java® applications, and mainframe/terminal-based applications running or being accessed from client devices. As explained above, access management system 120 may perform authentication of a user (e.g., user 102) operating a client device (e.g., device 104).

In some embodiments, access management system 140 may use one or more policies stored in a data store 180 (“policies”) to control access to resources. Policies 180 may include an authentication policy that specifies the authentication methodology to be used for authenticating the user for whom the access must be provided on a given resource. Policies 180 may include an access policy that defines the way in which the resource access is to be protected (e.g., type of encryption, or the like). Policies 180 may include an authorization policy that specifies the conditions under which a user or group of users has access to a resource. For example, an administrator may only authorize certain users within a group to access particular resources. Access management system 140 may determine authentication for an SSO session based on one or more of policies 180.

Access management system

140 may also include or be coupled to additional storage, which may be implemented using any type of persistent storage device, such as a memory storage device or other non-transitory computer-readable storage medium. In some embodiments, local storage may include or implement one or more databases (e.g., a document database, a relational database, or other type of database), one or more file stores, one or more file systems, or combinations thereof. For example, access management system 140 is coupled to or includes one or more data stores for storing data such as identity data store 150, session data cache 160 and policies 180. The memory and the additional storage are all examples of computer-readable storage media. For example, computer-readable storage media may include volatile or non-volatile, removable or non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules, or other data.

Session engine

142 may handle processing to determine whether a valid session exists for user 102 to access a resource. Access management system 140 may store session data in session data cache 160. In some embodiments, the rarely changing information (e.g., subject information) may be stored in session data cache 160. The subject information may be obtained from an identity data store 150. Session information that changes frequently may be sent to a client device for storage and received in communication from the client device. Session engine 142 checks for a valid session for user 102 to access a requested resource that is protected. Session engine 142 may assess validity of a session for user 102 based on consideration of one or more access policies applicable to user 102. Based on determining that a valid session does not exist for user 102, session engine 102 may request 108 credential information (“credentials”) from user 102. Successful authentication of the credential information may provide the user with access to one or more resources, which may include a requested resource.

Requests may be communicated to device 104 via communication network 170. A request may prompt user 102 for user credentials to determine authentication of a session. Request may include information (e.g., a URL) to a web page or a user interface (e.g., a web page, portal, or dashboard) to receive credential information.

Session engine

142 may perform operations to authenticate credential information for user 102. In some embodiments, session engine 142 may store information about sessions established upon successful authentication of a user. For a SSO session (e.g., SSO authenticated sessions), the SSO session may be managed as a SSO session enabling access to all resources accessible to user based upon successful authentication of credential information for a user.

In some embodiments, session engine 142 may communicate with authorization engine 144 regarding the scope of authentication. Session engine 142 can send the scope information received from device 104 to authorization engine 144. Authorization engine 144 can determine resources that are protected and based on authentication sessions, can determine resources that are permitted and/or restricted for a session.

In some embodiments, access management system 140 may be implemented in system 100 according to an agent-server model for communication between device 104 and any one of access manager servers implemented for access management system 140. The agent-server model may include an agent component (e.g., a gateway system) and a server component. The agent component may be deployed on a host system and the server component may be deployed on a server, e.g., an access manager server. User 102

operating device

104 may communicate with access management system 140 via agent using an enterprise computer network. In some embodiments, the agent may be an application or embedded in an application on device 104. Device 104 may be a workstation, personal computer (PC), laptop computer, smart phone, wearable computer, or other networked electronic device.

Agent may provide access control and may operate to protect access management system 140 and any resources accessible through access management system 140 against external and internal web-based threats. Access management system 140 may communicate with one or more resource computing systems (e.g., resource servers) that provide access to one or more resources, e.g., applications 120. Agent may implement or operate as the agent component access management system 140 and may include a server that operates as the server component. Each resource accessible by access management system 140 may be protected through an agent, e.g., agent. Agent may intercept user requests for one or more resources protected by it and check for user credentials in order to authenticate the user. The agent may then contact a server, e.g., an access manager server at access management system 140. The access management server may verify whether a resource is a protected resource that requires credentials for access. If the access management server determines that the resource is not protected, agent may grant access to user 102. If the resource is protected, agent may request user 102 to provide authentication credentials.

In some embodiments, communication between agent and access management system 140 may be split into two different channels of communication. For example, communication via a front-channel may use a hypertext transfer protocol secure (HTTPS) protocol. Front-channel communications may include less frequent communications, such as communications for credential collection operations for authentication. Communication via a back-channel may use an open access protocol (OAP). Back-channel communications may include more frequent communications, such as agent-server interactions including requests for access to a resource managed by access management system 140. Each channel may communicate using an access token designed for the type of communication over the channel. The access flow may generate two types of browser tokens. A first token is an access management ID token (e.g., OAM_ID token), which serves the SSO requests that are being propagated over HTTP. A second token is an authorization token (e.g., OAMAuthn Token) that may be used to server the SSO requests that are being propagated over OAP. The browser tokens may be stored as host cookies at device 104.

Access management system 140 (e.g., using agent) may present user 102 with a request for authentication credentials in the form of a challenge (e.g., via the user's web browser at device 104). In some embodiments, user 102 can access SSO user interface through a client executing on device 104 or through a web browser on device 104. The SSO user interface may be implemented at access management system 140. Access management system 140 may send, with request 108, the SSO user interface or information (e.g., a URL) enabling access to the SSO user interface.

In some embodiments, an SSO user interface can include a list of the applications user 102 commonly utilizes. User 102 can manage their credentials and policies associated with applications through the SSO user interface. When user 102 requests to access an application, e.g., application 140, through the SSO user interface, a request may be sent from device 104 to access management system 140 to determine a policy type for the application from one or more policies 160 applicable to user 102. Access management system 140 may determine whether a valid session exists for the user and if so, then it can determine user's 102 credential information based on the policy type.

In some embodiments, the request may include an authentication cookie from a previous login that can be used to determine whether user 102 is authorized to retrieve the credential. If authorized, the user can be logged into the application using the credential. In some embodiments, agent can enable users to access applications 120 using SSO services provided by access management system. Access may be provided through a web browser directly, without first accessing the SSO user interface or using a client executing on device 104. If user 102 is not authorized, then access management system may request 108 credentials from user 102. The SSO user interface may present an interface to receive input including credential information. The credential information may be sent 110 to access management system 140 to determine authentication of user 102.

In some embodiments, credential types can be supported, such as Oracle Access Management protected resources, federated applications/resources, and form-fill applications. Examples of credential types may include a Smartcard/Proximity card, a token, a public key infrastructure (PKI), a Windows Logon, a lightweight directory access protocol (LDAP) logon, a biometric input, or the like. For OAM protected resources, user requests can be authenticated and then directed to URLs associated with the requested resources. For Federated Applications, links to federated partners and resources can be provided, including business to business (B2B) partner applications and SaaS applications. For form fill applications, templates can be used to identify fields of application web pages through which credentials can be submitted.

II. Processes for Session Management

Access management system

140 can improve computing performance for management of session information by changing the way session information is stored. For example, for a user that authenticates from multiple clients, access management system 140 can optimize storage management and reduce processing by managing session information. Specific details about a session that change frequently may be managed individually for each session created for each user authenticated at a different client. Session information that is common, or shared between sessions created for a user at different clients may be stored centrally, in a distributed cache, where storage is abundant and the effects of delays caused by accessing the storage can be minimized.

The following operations in FIGS. 2-4 illustrate various exemplary embodiments by which access management system 140 can manage session information. Session information may be managed using the techniques disclosed herein to minimize computer performance issues for managing data about sessions. With the growth in mobile devices, users are increasingly accessing resources from many devices at any given time. The cost of computer resources may be too great for managing session information for multiple sessions across thousands of users.

In some embodiments, such as those described with reference to FIGS. 2-4, may be described as a process which is depicted as a flowchart, a flow diagram, a data flow diagram, a structure diagram, a sequence diagram, or a block diagram. Although a sequence diagram or a flowchart may describe the operations as a sequential process, many of the operations may be performed in parallel or concurrently. In addition, the order of the operations may be re-arranged. A process is terminated when its operations are completed, but could have additional steps not included in a figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. When a process corresponds to a function, its termination may correspond to a return of the function to the calling function or the main function.

The processes depicted herein, such as those described with reference to FIGS. 2 and 3, may be implemented in software (e.g., code, instructions, program) executed by one or more processing units (e.g., processors cores), hardware, or combinations thereof. The software may be stored in a memory (e.g., on a memory device, on a non-transitory computer-readable storage medium). In some embodiments, the processes depicted in flowcharts herein can be implemented by a computing system of an access management system, e.g., access management system 140 of FIG. 1. The particular series of processing steps in this disclosure are not intended to be limiting. Other sequences of steps may also be performed according to alternative embodiments. For example, alternative embodiments of the present disclosure may perform the steps outlined above in a different order. Moreover, the individual steps illustrated in the figures may include multiple sub-steps that may be performed in various sequences as appropriate to the individual step. While processing depicted in FIGS. 2-4 may be described with respect to accessing a single session by a user from multiple clients, such processing may be performed for multiple sessions, such that session information may be managed for multiple sessions for multiple users. Processing depicted in FIGS. 2-4 may be described with respect to multiple sessions, each for which session information may be managed. Furthermore, additional steps may be added or removed depending on the particular applications. One of ordinary skill in the art would recognize many variations, modifications, and alternatives.

In an aspect of some embodiments, each process in FIGS. 2-4 can be performed by one or more processing units. A processing unit may include one or more processors, including single core or multicore processors, one or more cores of processors, or combinations thereof. In some embodiments, a processing unit can include one or more special purpose co-processors such as graphics processors, digital signal processors (DSPs), or the like. In some embodiments, some or all of processing units can be implemented using customized circuits, such as application specific integrated circuits (ASICs), or field programmable gate arrays (FPGAs).

FIG. 2 illustrates a sequence diagram showing operations 200 for managing session information, in accordance with an embodiment. Specifically, the operations 200 may be performed by some or all of the elements shown with respect to FIG. 1. The examples shown in FIGS. 2 and 3 are with respect to a single user operating each of client 202 (e.g., “client1”), client 204 (e.g., “client2”), and client 206 (e.g., “client3”). For purposes of explanation, a client in FIGS. 2 and 3 is a device; however, a client can be a device or an application on a device.

Access management system

140 may store and persist session information in a distributed storage system. The distributed storage system may include one or more memory devices implemented as a cache for fast read and write operations. In a distributed environment where multiple computing devices are distributed as a cluster of computing nodes, each corresponding to a computing device, for an access management system, the distributed cache system provides high performance for computing nodes in the cluster.

Access management system

140 may designate session information for a session into two different categories: 1) session information that does not change often or that rarely changes during an active session; and 2) session information that changes frequently during an active session. Session information may be designated for management based on one or more criteria. The criteria may be configurable and adjusted based on assessment of processing performance and/or availability of resources.

To create subject information upon establishing an access session, an identity store may be accessed for a subject, which may have the attributes of user as well as group membership information of the user. As the subject information changes less frequently, the possibility of a change in the subject information is not likely. Access management system 140 may store subject information in a data store, such as a highly distributed cache optimized for current reads for multiple sessions. The session information may be stored based on identity store name and a dataset name. During subsequent accesses the subject will be retrieved from session data stored by access management system 140, such that access to identity store may not be necessary. Avoiding access to the identity store can reduce or eliminate querying the identity store during subsequent access using an existing session. Information about a subject is an example of information that does not change often. If access for a user is locked, then the session data stored may be updated by access management system 140 to indicate that the account is locked.

To minimize perform overhead, access management system 140 may split session information into two categories: 1) data in session that does not change or changes rarely during the lifetime of a server side session; and) data in session that changes frequently during lifetime of a server side session. Examples of data that does not change or rarely changes is subject information for a user (e.g., authenticated user subject information) that may remain status across multiple sessions for the user. Depending on the category of session data, session data may be stored differently thereby reducing performance overhead for storage and access of session data.

Data about a session that changes frequently and may be specific to a session may be stored different than data that does not change frequently. In some embodiments, session data that changes frequently can be stored in scalable, distributed cache that is optimized for frequent updates. In some embodiments, data that changes frequently can be managed such that access management system 140 passes it to the client (e.g., user-agent or device), which can pass the information back to access management system 140 in a request for access. Access management system, can reconstruct and identify a session based on the data that is received back from the client.

In some embodiments, rarely changing data may be stored in a highly scalable, distributed cache. The distributed optimized for distributed reads. In the example shown in FIG. 2, common attributes 240 (e.g., subject information) may be stored in a highly distributed cache that is accessible by access management system 140. Common attributes 240 may be stored for a user having multiple access sessions, session 216 (“session 1”), session 226 (“session 2”), and session 236 (“session 3”), from client 202, client 204, and client 206, respectively. Because common attributes 222 changes rarely, such information may be accessed once from an identity store and stored locally in distributed cache. If access for a user is locked, then the cache may be updated by access management system 140 to indicate that the account is locked for the subject, thereby minimizing updates for multiple sessions.

Now turning to the example in FIG. 2, a user (“User1”) may operate a first client 202 (“client1”) to establish a session 216 (“session1”) for access. Access management system 140 may manage access to resources from any one of the

clients

202, 204, 206 operated by a user.

At step 210, Client 202 may request access for User1. The request may be for access to one or more resources. At step 212, access management system 140, may determine whether a user was previously authenticated for access at a client. If access is managed according to techniques for SSO, then access management system 140 may determine whether the user was authenticated at any client. Access management system 140 may communicate with client 202 to request and obtain credentials to authenticate User1 if User1 is determined to not be authenticated. User1 may not be authenticated upon expiration of access according to one or more criteria for access management. Upon successful authentication of User1, access management system 140 may create session 216 (“session1”). As part of creating the session, access management system 140 may store session data 218 (“specific attributes”) that includes information, such as specific attributes about the session. Specific attributes may include information identified as changing frequently, such as list of partners accessed in session, IP Address of the client device, authentication level, authentication scheme, authentication timestamp, and application domain information for accessed resources. The specific attributes, such as access timestamp, partner information of a last accessed resource, and application domain information for one or more accessed resources, may be updated each time User1 requests access (e.g., request authorization for a resource or request authentication for a session).

In some embodiments, specific attributes may be stored using a variety of techniques to improve processing performance for access management system 140, by reducing an amount and type of operations for data that changes frequently. For example, access management system 140 may utilize a distributed, highly scalable cache for frequent updates to reduce the impact of processing based on frequent operations to store and retrieve. In another example, access management system 140 may limit storage of session information to information that does not change frequently, such as common attributes. Access management system 140 can access the common attributes when needed for each session. Information that changes frequently may be sent to a client with access information (e.g., a token). Session information corresponding to specific attributes may not be stored locally by access management system 140 may be sent to the client with information (e.g., a token) related to access for a session. The information may be an access claim, such that the client is provided with access based on providing the specific attributes along with the information related to access for a session.

After session1 is created, at step 214, access management system 140 may send a response (“signed access claim”) including a portion of the session information, such as specific attributes 218, to client 202. The response may be pre-defined. The signed access claim may include an identity store identifier and/or a domain name (DN) identifier of the authenticated user so access management system 140 can retrieve the common attributes 240 for a session when needed. Client 202 may store information in the signed access claim locally at client 202 for subsequent access requests. Client 202, on subsequent requests, can send the signed access claim to access management system 140. Access management system 140, when updating or establishing a new session, can use the signed access claim to identify common attributes for the session. The information in the signed access claim may be used to retrieve the common attributes from the common store for the sessions.

After session1 216 is created, User1 may continue to operate client 202 to access resources using session1 216. Upon each subsequent access for a resource, client 202 may send access information including a signed access claim to utilize the session1 216. Access management system 140 may use the signed access claim to recreate the session information for session 1 216. The specific attributes for the session information may be recreated based on the signed access claim included in the access information for a subsequent request. The specific attributes may be updated upon a subsequent access using session1 216. The specific attributes may be sent back to client 202 as a signed access claim with information about the request for access. Since the specific attributes may not be stored by access management system 140, access management system 140 may not incur performance overhead for storing the information and distributed locking may not need to be implemented since the specific attributes for each session are not stored centrally by access management system 140.

After session1 216 is created, User1 may operate a second client 204 (“client2”) to establish a session 226 (“session2”) for access. At step 220, Client 204 may request access for User1. At step 222, access management system 140, may upon verification of User1's credentials, create session2 226. Access management system 140 may determine authentication of User1 for session 2 226 based on a previous authentication when SSO is implemented. As part of creating the session2 226, access management system 140 may store session data 228 (“specific attributes”) that includes information, such as specific attributes about the session2 226. However, since a previous session (e.g., session 216) was created, common attributes 240 for a session have been retrieved and stored in a distributed cache. To minimize performance overhead, access management system 140 may access or reference the common attributes 240 to create session2 226. For the new session, session2 226, access management system may determine specific attributes 228. Frequently changing session information, such as specific attributes 228, for session2 226 may be stored locally for frequent updates. At step 224, access management system 140 may send a response to client 204 (“signed access claim”). The response may include the specific attributes and the information identifying the common attributes 240 (e.g., identity store identifier or DN identifier). Similar to session 216, access management system 140 can find common attributes when client 204 sends the signed access claim with a request for access.

After session2 is created, User1 may operate a third client 206 (“client3”) to establish a session 236 (“session3”) for access. At step 230, Client 206 may request access for User1. At step 232, access management system 140, may upon verification of User1's credentials, create session3 236. Access management system 140 may determine authentication of User1 for session 3 236 based on a previous authentication when SSO is implemented. As part of creating the session3 236, access management system 140 may store session data 238 (“specific attributes”) that includes information, such as specific attributes about the session3 236. However, since a previous session (e.g., session 216) was created, common attributes for a session have been retrieved and stored in a distributed cache. To minimize performance overhead, access management system 140 may access or reference the common attributes 240 to create session3 236. Frequently changing session information, such as specific attributes 238, for session3 236 may be stored locally for frequent updates. At step 234, access management system 140 may send a response to client 206 (“signed access claim”). The response may include the specific attributes 238. Similar to session 216 and session2 226, access management system 140 can find common attributes when client 206 sends the signed access claim with a request for access.

With this approach, there is common information may not be stored per session for a unique user. Access management system 140 may limit storage of session information to a single instance regardless of the number of sessions created for the same user across one or more clients. If server side session usage tracking is required, then a minimalist session per user login can be created which would refer to common subject information. This will reduce the storage and access footprint at access management system 140 to a great extent and optimize memory utilization of access management system 140. The frequently changing session information may not need to be stored locally and can instead be obtained from a signed access claim, which can be used to reconstruct a session in combination with the common attributes 240.

Now turning to FIG. 3 is a sequence diagram showing operations 300 for managing session information, in accordance with an embodiment. FIG. 3 shows how access management system 140 can manage session information to reduce memory storage and minimize storage footprint for multiple sessions, especially, in a distributed computing environment. Elements in FIG. 3 may be referenced from figures in this disclosure.

The example shown in FIG. 3 continues from the examples in FIG. 2. At step 302, client 202 may request access to a resource via an access management system 140. The request may include an access claim that was sent to the client previously after a previous access (e.g., when a session was established). An access claim may include session information that changes frequently such as disclosed above. An access claim may include an identifier of a data store including subject information about a user. An access claim may include user access information (e.g., a domain name of a user) that is part of session information that does not change frequently. At step 304, access management system 140 may determine whether a session was established. The access claim may be used to reconstruct session information for a session. Access management system 140 may access a distributed cache where rarely changing subject information is stored. Using the identifier in the access claim, access management system 140 may identify subject information from the cache. The session may be reconstructed using the session information in the access claim.

When a session does not exist for a resource, access management system 140 may establish a session based on the subject information. A new access claim may be created for the session.

Access management system

140 may update the session information in the access claim upon accessing a resource for the session. The session information may also be updated if the access management system 140 requests credential information from client 202 for reauthentication or step-up authentication. The updated session information may be updated to the access claim.

In some embodiments, if access is locked for a user, the subject information in the cache may be updated to indicate that access is locked. Upon subsequent requests for access, the subject information may indicate that the access is locked such that no client can obtain access until the account is unlocked. When the account is unlocked, the cache may be updated for the subject information. Thus, a single source of the subject information reduces overhead in distributed locking or delays in access concurrently for different clients.

At step 306, access management system 140 may send the updated access claim or a new access claim to client 202 for storage. In this case updating the access claim and sending it back to the client 202 may not cause any performance overhead since distributed locking may not be used.

Similarly, at step 312, client 204 may request access to a resource. The request may include an access claim sent from access management system 140 to client 204 for a previous access. As explained above for step 304, at step 314, access management system may use the access claim to obtain the subject information from the cache. All the sessions will be referring to subject information which can be retrieved from cache. Even if same user logs-in from different clients/devices, only single subject information will be available in the cache; which will be shared by all sessions of same user. Also this same identity store information and user DN will be part of all the access claims for a user.

Access management system

140 can determine session status based on the access claim. Access management system 140 can determine whether the account of the user is locked based on the subject information. If necessary, access management system 140 can determine the session based on the access claim, and if necessary establish a new session. Access management can determine authorization and whether additional credentials are necessary. The access claim can be updated based on the session activity.

At step 316, access management system can send a response including the access claim with updates to the session information.

Now turning to FIG. 4, is a flowchart 400 of a process for managing session information according to some embodiments. Flowchart 400 may be implemented by access management system 140 of FIG. 1.

Flowchart

400 may begin at step 402 by receiving a request by a user to access one or more resources at the device. At step 404, information (e.g., subject information) about the user is obtained from a data store of an access management system. The data store can be implemented as a cache accessible in a distributed manner to the access management system. The information may include user identity information. The user identify information may include user access information such as a domain name of the user.

At step 406, authentication of the user to access one or more resources may be determined. At step 408, using information about the user obtained from an identity data store and based on authentication of the user for access to one or more resources, a session for a user of a device is established to access one or more resources. The session information is generated for one or more attributes of the session. The session information may include a list of partners accessed in session, an Internet protocol (IP) address of the device, an authentication level of the session, an authentication scheme of the session, an authentication timestamp of the session, application domain information for one or more accessed resources using the session, or combinations thereof.

At step 410, information about the user is stored in a data store of the access management system. The information is associated with an identifier. At step 412, a response about the session that is established is sent to the device. The response includes the session information, the identifier, and the user access information. The identifier may indicate an identification of the data store. The response may include an access token generated to enable access to the session. At step 414, a request for access to a resource is received from the device. The request includes the session information, the identifier, and the user access information. The request may include the access token. At step 416, based on the identifier and the user access information, the information about the user is accessed from the data store. At step 418, based on the session information and the information accessed from the data store, the session established for the user is determined. At step 420, based on authorization of the user to access the resource, the user is provided at the device with access to the resource based on the determined session. At step 422, the session information is updated based on the access to the resource using the session. At step 424, the updated session information is sent to the device.

In some embodiments, based on the information accessed about the user, access by the session is determined to be locked. Instead of providing the user with access to the resource, the user may be denied at the device with access to the resource based on the determined session.

In some embodiments, the request at step 414 is a first request. The session is a first session. The device is a first device. The session information is first session information. Flowchart may include establishing a second session for the user to access the resource at a second device. A response may be sent to the second device about the second session that is established. The response includes second session information, the identifier, and the user access information. A second request may be received from the second device for access to the resource, the request including the second session information, the identifier, and the user access information. Based on the identifier and the user access information in the second request, the information about the user may be accessed from the data store. Based on the second session information and the information accessed from the data store, the second session may be determined as established for the user. Based on authorization of the user to access the resource, the user may be provided at the second device with access to the resource based on the determined second session. The second session information may be updated based on the access to the resource using the second session. The updated second session information may be sent to the second device. In some embodiments, based on the information about the user, a determine is made that access by the second session is locked. Instead of providing the second device with access to the resource, the user at the second device may be denied with access to the resource based on the determined second session.

In some embodiments, the request at step 414 is a first request. The resource is a first resource. A second request by the user at the device may be received to access a second resource, the second request including the session information, the identifier, and the user access information. Based on the identifier and the user access information in the second request, the information about the user may be accessed from the data store. Based on the session information and the information accessed from the data store, the session established for the user may be determined. Based on authorization of the user to access the second resource, the user at the device may be provided with access to the second resource based on the determined session. The session information may be updated based on the access to the second resource using the session. The updated session information based on the access to the second resource may be sent to the second device. In some embodiments, a determination is made that access to the second resource is based on additional authentication of the user. The session information may be updated for the second resource to indicate the additional authentication.

Flowchart

400 may end at step 426.

In the illustrated embodiment in FIG. 6, system environment 600 includes one or more

client computing devices

604, 606, and 608 that may be used by users to interact with a cloud infrastructure system 602 that provides cloud services. Cloud infrastructure system 602 may comprise one or more computers and/or servers that may include those described above for server 512.

It should be appreciated that cloud infrastructure system 602 depicted in FIG. 6 may have other components than those depicted. Further, the embodiment shown in FIG. 6 is only one example of a cloud infrastructure system that may incorporate an embodiment of the disclosure. In some other embodiments, cloud infrastructure system 602 may have more or fewer components than shown in the figure, may combine two or more components, or may have a different configuration or arrangement of components.

Client computing devices

604, 606, and 608 may be devices similar to those described above for

client computing devices

502, 504, 506, and 508.

Client computing devices

604, 606, and 608 may be configured to operate a client application such as a web browser, a proprietary client application (e.g., Oracle Forms), or some other application, which may be used by a user of the client computing device to interact with cloud infrastructure system 602 to use services provided by cloud infrastructure system 602. Although exemplary system environment 600 is shown with three client computing devices, any number of client computing devices may be supported. Other devices such as devices with sensors, etc. may interact with cloud infrastructure system 602.

Network(s) 610 may facilitate communications and exchange of data between

client computing devices

604, 606, and 608 and cloud infrastructure system 602. Each network may be any type of network familiar to those skilled in the art that can support data communications using any of a variety of commercially-available protocols, including those described above for network(s) 510.

In certain embodiments, services provided by cloud infrastructure system 602 may include a host of services that are made available to users of the cloud infrastructure system on demand. Various other services may also be offered including without limitation online data storage and backup solutions, Web-based e-mail services, hosted office suites and document collaboration services, database processing, managed technical support services, and the like. Services provided by the cloud infrastructure system can dynamically scale to meet the needs of its users.

In certain embodiments, a specific instantiation of a service provided by cloud infrastructure system 602 may be referred to herein as a “service instance.” In general, any service made available to a user via a communication network, such as the Internet, from a cloud service provider's system is referred to as a “cloud service.” Typically, in a public cloud environment, servers and systems that make up the cloud service provider's system are different from the customer's own on-premises servers and systems. For example, a cloud service provider's system may host an application, and a user may, via a communication network such as the Internet, on demand, order and use the application.

In some examples, a service in a computer network cloud infrastructure may include protected computer network access to storage, a hosted database, a hosted web server, a software application, or other service provided by a cloud vendor to a user, or as otherwise known in the art. For example, a service can include password-protected access to remote storage on the cloud through the Internet. As another example, a service can include a web service-based hosted relational database and a script-language middleware engine for private use by a networked developer. As another example, a service can include access to an email software application hosted on a cloud vendor's web site.

In certain embodiments, cloud infrastructure system 602 may include a suite of applications, middleware, and database service offerings that are delivered to a customer in a self-service, subscription-based, elastically scalable, reliable, highly available, and secure manner. An example of such a cloud infrastructure system is the Oracle Public Cloud provided by the present assignee.

Cloud infrastructure system

602 may also provide “big data” elated computation and analysis services. The term “big data” is generally used to refer to extremely large data sets that can be stored and manipulated by analysts and researchers to visualize large amounts of data, detect trends, and/or otherwise interact with the data. This big data and related applications can be hosted and/or manipulated by an infrastructure system on many levels and at different scales. Tens, hundreds, or thousands of processors linked in parallel can act upon such data in order to present it or simulate external forces on the data or what it represents. These data sets can involve structured data, such as that organized in a database or otherwise according to a structured model, and/or unstructured data (e.g., emails, images, data blobs (binary large objects), web pages, complex event processing). By leveraging an ability of an embodiment to relatively quickly focus more (or fewer) computing resources upon an objective, the cloud infrastructure system may be better available to carry out tasks on large data sets based on demand from a business, government agency, research organization, private individual, group of like-minded individuals or organizations, or other entity.

In various embodiments, cloud infrastructure system 602 may be adapted to automatically provision, manage and track a customer's subscription to services offered by cloud infrastructure system 602. Cloud infrastructure system 602 may provide the cloud services via different deployment models. For example, services may be provided under a public cloud model in which cloud infrastructure system 602 is owned by an organization selling cloud services (e.g., owned by Oracle Corporation) and the services are made available to the general public or different industry enterprises. As another example, services may be provided under a private cloud model in which cloud infrastructure system 602 is operated solely for a single organization and may provide services for one or more entities within the organization. The cloud services may also be provided under a community cloud model in which cloud infrastructure system 602 and the services provided by cloud infrastructure system 602 are shared by several organizations in a related community. The cloud services may also be provided under a hybrid cloud model, which is a combination of two or more different models.

In some embodiments, the services provided by cloud infrastructure system 602 may include one or more services provided under Software as a Service (SaaS) category, Platform as a Service (PaaS) category, Infrastructure as a Service (IaaS) category, or other categories of services including hybrid services. A customer, via a subscription order, may order one or more services provided by cloud infrastructure system 602. Cloud infrastructure system 602 then performs processing to provide the services in the customer's subscription order.

In some embodiments, the services provided by cloud infrastructure system 602 may include, without limitation, application services, platform services and infrastructure services. In some examples, application services may be provided by the cloud infrastructure system via a SaaS platform. The SaaS platform may be configured to provide cloud services that fall under the SaaS category. For example, the SaaS platform may provide capabilities to build and deliver a suite of on-demand applications on an integrated development and deployment platform. The SaaS platform may manage and control the underlying software and infrastructure for providing the SaaS services. By utilizing the services provided by the SaaS platform, customers can utilize applications executing on the cloud infrastructure system. Customers can acquire the application services without the need for customers to purchase separate licenses and support. Various different SaaS services may be provided. Examples include, without limitation, services that provide solutions for sales performance management, enterprise integration, and business flexibility for large organizations.

In some embodiments, platform services may be provided by cloud infrastructure system 602 via a PaaS platform. The PaaS platform may be configured to provide cloud services that fall under the PaaS category. Examples of platform services may include without limitation services that enable organizations (such as Oracle) to consolidate existing applications on a shared, common architecture, as well as the ability to build new applications that leverage the shared services provided by the platform. The PaaS platform may manage and control the underlying software and infrastructure for providing the PaaS services. Customers can acquire the PaaS services provided by cloud infrastructure system 602 without the need for customers to purchase separate licenses and support. Examples of platform services include, without limitation, Oracle Java Cloud Service (JCS), Oracle Database Cloud Service (DBCS), and others.

By utilizing the services provided by the PaaS platform, customers can employ programming languages and tools supported by the cloud infrastructure system and also control the deployed services. In some embodiments, platform services provided by the cloud infrastructure system may include database cloud services, middleware cloud services (e.g., Oracle Fusion Middleware services), and Java cloud services. In one embodiment, database cloud services may support shared service deployment models that enable organizations to pool database resources and offer customers a Database as a Service in the form of a database cloud. Middleware cloud services may provide a platform for customers to develop and deploy various business applications, and Java cloud services may provide a platform for customers to deploy Java applications, in the cloud infrastructure system.

Various different infrastructure services may be provided by an IaaS platform in the cloud infrastructure system. The infrastructure services facilitate the management and control of the underlying computing resources, such as storage, networks, and other fundamental computing resources for customers utilizing services provided by the SaaS platform and the PaaS platform.

In certain embodiments, cloud infrastructure system 602 may also include infrastructure resources 630 for providing the resources used to provide various services to customers of the cloud infrastructure system. In one embodiment, infrastructure resources 630 may include pre-integrated and optimized combinations of hardware, such as servers, storage, and networking resources to execute the services provided by the PaaS platform and the SaaS platform, and other resources.

In some embodiments, resources in cloud infrastructure system 602 may be shared by multiple users and dynamically re-allocated per demand. Additionally, resources may be allocated to users in different time zones. For example, cloud infrastructure system 602 may enable a first set of users in a first time zone to utilize resources of the cloud infrastructure system for a specified number of hours and then enable the re-allocation of the same resources to another set of users located in a different time zone, thereby maximizing the utilization of resources.

In certain embodiments, a number of internal shared services 632 may be provided that are shared by different components or modules of cloud infrastructure system 602 to enable provision of services by cloud infrastructure system 602. These internal shared services may include, without limitation, a security and identity service, an integration service, an enterprise repository service, an enterprise manager service, a virus scanning and white list service, a high availability, backup and recovery service, service for enabling cloud support, an email service, a notification service, a file transfer service, and the like.

In certain embodiments, cloud infrastructure system 602 may provide comprehensive management of cloud services (e.g., SaaS, PaaS, and IaaS services) in the cloud infrastructure system. In one embodiment, cloud management functionality may include capabilities for provisioning, managing and tracking a customer's subscription received by cloud infrastructure system 602, and the like.

In one embodiment, as depicted in FIG. 6, cloud management functionality may be provided by one or more modules, such as an order management module 620, an order orchestration module 622, an order provisioning module 624, an order management and monitoring module 626, and an identity management module 628. These modules may include or be provided using one or more computers and/or servers, which may be general purpose computers, specialized server computers, server farms, server clusters, or any other appropriate arrangement and/or combination.

In an exemplary operation, at step 634, a customer using a client device, such as

client computing devices

604, 606 or 608, may interact with cloud infrastructure system 602 by requesting one or more services provided by cloud infrastructure system 602 and placing an order for a subscription for one or more services offered by cloud infrastructure system 602. In certain embodiments, the customer may access a cloud User Interface (UI) such as cloud UI 612, cloud UI 614 and/or cloud UI 616 and place a subscription order via these UIs. The order information received by cloud infrastructure system 602 in response to the customer placing an order may include information identifying the customer and one or more services offered by the cloud infrastructure system 602 that the customer intends to subscribe to.

At step 636, the order information received from the customer may be stored in an order database 618. If this is a new order, a new record may be created for the order. In one embodiment, order database 618 can be one of several databases operated by cloud infrastructure system 618 and operated in conjunction with other system elements.

At step 638, the order information may be forwarded to an order management module 620 that may be configured to perform billing and accounting functions related to the order, such as verifying the order, and upon verification, booking the order.

At step 640, information regarding the order may be communicated to an order orchestration module 622 that is configured to orchestrate the provisioning of services and resources for the order placed by the customer. In some instances, order orchestration module 622 may use the services of order provisioning module 624 for the provisioning. In certain embodiments, order orchestration module 622 enables the management of business processes associated with each order and applies business logic to determine whether an order should proceed to provisioning.

As shown in the embodiment depicted in FIG. 6, at step 642, upon receiving an order for a new subscription, order orchestration module 622 sends a request to order provisioning module 624 to allocate resources and configure resources needed to fulfill the subscription order. Order provisioning module 624 enables the allocation of resources for the services ordered by the customer. Order provisioning module 624 provides a level of abstraction between the cloud services provided by cloud infrastructure system 600 and the physical implementation layer that is used to provision the resources for providing the requested services. This enables order orchestration module 622 to be isolated from implementation details, such as whether or not services and resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request.

At step 644, once the services and resources are provisioned, a notification may be sent to the subscribing customers indicating that the requested service is now ready for use. In some instance, information (e.g. a link) may be sent to the customer that enables the customer to start using the requested services.

At step 646, a customer's subscription order may be managed and tracked by an order management and monitoring module 626. In some instances, order management and monitoring module 626 may be configured to collect usage statistics regarding a customer use of subscribed services. For example, statistics may be collected for the amount of storage used, the amount data transferred, the number of users, and the amount of system up time and system down time, and the like.

In certain embodiments, cloud infrastructure system 600 may include an identity management module 628 that is configured to provide identity services, such as access management and authorization services in cloud infrastructure system 600. In some embodiments, identity management module 628 may control information about customers who wish to utilize the services provided by cloud infrastructure system 602. Such information can include information that authenticates the identities of such customers and information that describes which actions those customers are authorized to perform relative to various system resources (e.g., files, directories, applications, communication ports, memory segments, etc.) Identity management module 628 may also include the management of descriptive information about each customer and about how and by whom that descriptive information can be accessed and modified.
